Desorption of chromium (VI) and lead (II) ions and regeneration of the exhausted adsorbent

Abstract: The desorption characteristics of previously adsorbed hexavalent chromium [Cr(VI)] and divalent lead [Pb(II)] ions on groundnut husk were tested by various desorption eluents such as tap water, de-ionized water, NaOH, HCl and H2SO4 Among them, HCl and H2SO4 were chosen as the best desorbing agents for Cr(VI) and Pb(II) ions, respectively, due to their high desorption efficiency The desorption efficiency of HCl and H2SO4 for Cr(VI) and Pb(II) ions was about 761% and 821%, respectively, at a concentration of 01 M for both elution agents The exhausted groundnut husk was regenerated up to five cycles, and the removal efficiency of Cr(VI) and Pb(II) ions on the recycled groundnut husk could be maintained at 535% and 546%, respectively, in the third cycle The successive regeneration cycles resulted in the reduction of the desorption efficiency by 200% and 267% for Cr(VI) and Pb(II) ions, respectively, after the third cycle The results show that groundnut husk could be recycled when used to remove Cr(VI) and Pb(II) ions from Cr(VI) and Pb(II)-polluted water and wastewaters

Adoption of Internet Technology by the Banking Industry in Oman: A Study Informed by the Australian Experience

Abstract: The banking industry in Oman is of major importance to Oman’s economy, yet Omani banks continue to conduct most of their transactions using traditional methods A strong banking industry significantly supports economic development through efficient financial services, and their role in trying to achieve the objectives outlined by the Sultan of Oman will depend heavily on the industry’s capabilities Omni banks will need to introduce change at both procedural and informational levels that includes moving from traditional distribution channel banking to electronic channel banking This paper addresses the question: What are the enablers and the inhibitors of Internet technology adoption in the Omani banking industry compared with those in the Australian banking industry? The paper does not attempt a direct comparison of the banking industries in these two very different countries, but rather presents a discussion of Internet technology adoption in Oman, informed by the more mature Australian experience
